Uninstaller for amd catalyst /usr/share/ati/amd-uninstall.sh, does not exist or cannot be found

I am unable to uninstall the AMD Catalyst driver using the script specified by the AMD instructions here.

When I run the command:

sudo ./amd-driver-installer-13.35.1005-x86.x86_64.run --uninstall 

I get the error below:

uninstaller for amd catalyst /usr/share/ati/amd-uninstall.sh, does not exist or cannot be found

How can I remove these drivers now?

Removing Catalyst/fglrx

The uninstall script in the first command will only exist if you downloaded the drivers and installed them directly (rather than building packages as this guide does). Skip the first command if it does not exist.

sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx*

If you plan on using open-source drivers, you will need to reinstall some packages because Catalyst overwrites or diverts some key 3D libraries with proprietary versions. For more information on this issue, see this Ubuntu wiki page

sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get install xserver-xorg-video-ati
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
sudo rm -f /etc/ati

If you receive

$ E: Internal Error, No file name for libgl1-mesa-dri

Change the third command above to:

sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:i386 libgl1-mesa-dri:amd64 xserver-xorg-core
